Embodiment approach

[0043] (1): When the configuration information includes the position of the TV transmission tower and the tower height of the TV transmission tower, the base station is based on the position of the TV transmission tower and the tower height of the TV transmission tower and the position of the base station and the The tower height of the base station obtains the angle of arrival at which the TV transmission tower reaches the base station.

[0044] (2): When the configuration information also includes the system of the TV transmission tower and its corresponding mode and pilot type, then channel estimation is performed on the TV signal through the system and its corresponding mode and pilot type, and the estimated channel Obtain the angle of arrival from the TV tower to the base station, and design beamforming based on the angle of arrival.

[0045] In the above case (2), the standard of the TV tower and its corresponding mode and pilot type can also be obtained when the TV towe...

Abstract

The invention relates to the technical field of cognition wireless, and provides a method and device for suppressing interference. The method for suppressing interference comprises the following steps of receiving configuration information, sent by a database, of a TV launching tower, wherein the configuration information comprises launching power, working frequency points of the TV launching tower, the position of the TV launching tower and the height of the TV launching tower, judging whether a base station is interfered by TV signals according to the configuration information, the position of the base station and the tower height of the base station, and when the base station is interfered by the TV signals, obtaining the direction of arrival from the TV launching tower to the base station according to the configuration information to conduct wave beam forming on the TV signals according to the direction of arrival. By the adoption of the method and device for suppressing interference, the goal of suppressing the interference of the TV signals in the base station is achieved, and the utilization rate of the frequency spectrum of TVWS is maximized.

Description

technical field [0001] Embodiments of the present invention belong to the technical field of cognitive radio (Cognitive Radio, CR), and in particular relate to an interference suppression method and device. Background technique [0002] By sensing the wireless spectrum environment, CR technology can dynamically access unoccupied frequency bands without interfering with primary users (users who used the fixedly allocated frequency bands), and realize the use of frequencies in a seamless manner, thereby improving spectrum utilization. At present, both the Reconfigurable Radio System Standards Group of the European Telecommunications Standards Institute and the IEEE Standards Association are determined to standardize the CR technology in the TV White Space (TVWS) field. TVWS refers to the frequency band where digital TV works, for example, TVWS in China is 470MHz-806MHz. Since the digital TV transmission towers all have the characteristics of geographical multiplexing, for exa...
